WIRE FABRIC FOR BELTS OR APRONS.

SPECIFICATION formingpart of Letters Patent No. 712,212, dated October 28, 1902 Application filed October 7, 1901.

To all whom it may concern:

Be it known that I, CHARLES SWINSCOE, of Clinton, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Wire Fabric for Belts or Aprons, of which the following is a specification.

This invention relates to woven-wire fabrics especially adapted for use for belts or aprons of relatively large size. Such fabrics are usually composed of helical wire members extending crosswise of the belt, their convolutions being interlocked at their ends to form selvages at the edges of the fabric and interwoven or interlocked at intermediate points to form a woven fabric. The outer and inner portions of said convolutions form practically continuous diagonal ribs onjthe outer and inner sides of the belt, the ribs at the inner surface of the belt bearing on the supporting drums or pulleys. Heretofore the structure of fabrics of this oharacterhas been such that all the diagonal ribs at the inner side of the belt are parallel with each other and extend in the same direction, all the ribs at the outer side of the belt being also parallel with each other. The diagonal arrangement of the ribs gives the fabric a tendency to creep or crawl edgewise in one direction on the drums or pulleys and causes a liability to bodily edgewise displacement of the beltin one direction.

My invention has for its object to prevent this liability; and it consistsin a wire fabric for a belt or apron composed of sections joined together, the wire members of each section being arranged to counteract any tendency to edgewise displacement in the other section.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents. a plan view of a portion of a wire fabric for a belt or apron embodying my invention. Fig. 2 represents a similar view showing a dilferent embodiment of my invention.

The same reference characters indicate the same parts in all the figures.

The wire fabric shown in the drawings is composed of a multiplicity of helical wire members extending crosswise of the fabric, the convolutions of each member being interlocked or interwoven with the convolutions of the adjacent members, the arrangement being such that outer portions 1 1 of said con- Serial No. 77,787. (No specimens.)

volutions collectively constitute outer diagonal ribs on the outer side of the fabric, while the inner portions 2 2 of said convolutions constitute inner diagonal ribs on the inner side of the fabric. The said portions 1 and 2 may be termed the outer and inner surface portions of the members. The said inner ribs bear on the supporting drums or pulleys and have a tendency to slide or creep in the direction of their length, thus causing bodily edgewise displacement of the belt in the same direction.

In carrying out my invention I construct the fabric in two or more sections, each of which is so woven as to counteract the tendency of the adjacent section or sections to' creep edgewise or diagonally.

In Fig. 1 I show the fabric divided into two longitudinal sections a a, in one of which the said diagonal ribs extend in a direction opposite to the direction of the diagonal ribs of the other section. Assuming the direction of movement of the belt to be as indicated by the arrow b, the tendency of the section a is to creep in the direction of the arrow 17, while the tendency of the section a is to creep in the direction of the arrow 6 Hence the tendency of each section to creep is neutralized and the belt runs without material edgewise displacement. The two sections a and a are joined together in this embodiment of my invention by means of interlocked eyes or loops formed on the meeting ends of the helical wire members of the sections.

In Fig. 2 I show the fabric made up of alternating sections 0 and'c', each extending entirely across the fabric. In the sections 0 the direction of the diagonal ribs is opposite to that of the ribs in the sections 0, the tendency of the sections to creep being as indicated by the arrows marked thereon. The result of this construction is practically the same as that of the construction shown in Fig. l. The sections 0 and c are joined together by transverse coupling-wires 4, threaded through meeting portions of the convolutions of the end members of the sections.

5 5 represent longitudinal cords or ligatures threaded through the edge portions of the belt to confine said edge portions.

I claim- 1. A wire fabric composed of sections joined together and each composed of interlocked wire members having inclined surface portions,the surface portions of each section being inclined oppositely to the surface portions of the adjacent section, whereby tendency to edgewise displacement in either section is counteracted by the other section.

2. A wire fabric composed of interwoven helical wire members extending crosswise of the fabric and having convolutions which form diagonal ribs at opposite sides of the fabric, the inclination of said ribs in a given portion of the fabric being opposite to that of the ribs in another portion, substantially x 5 as and for the purpose specified.

3. A wire fabric composed of a plurality of transverse sections each extending entirely across the fabric, and each composed of interwoven helical wire members extending crosswise of the fabric, the inclination of the convolutions of each section being opposite to that of the convolutions of the next section, and transverse coupling-wires connecting the meeting ends of the sections.

In testimony whereof I have affixed my signature in presence of two witnesses.

CHARLES SWINSOOE.
